Work has recently commenced on connecting the South Shed to the museum’s main power supply. A trench has been excavated to allow ducting to be laid between the shed, and the No. 2 substation where 415v mains is available.
Conduits pass through the wall and under the track. 
Electrical pits have been laid next to the National Park line. These provide the change of direction for the ducts, which then run underground alongside the track to the No.2 substation.

More conduits have been laid and the trench extended towards the substation.
April 2020
A further series of conduits and a new power switch have been bolted to a nearby overhead pole, and the trench filled in.
Meanwhile, cable trays have been installed inside the shed itself to allow for future wiring to run above ground, and reach the power box that’s located on the highway side of the shed.

Closer to No.2 Substation, a new trench was recently dug out to allow new conduits for the South Shed power supply to be laid. This was work was done within a few weeks and the trench has now been filled in.
Conduits pass up into the floor of the substation to allow for new cables to be run through and connected up to the existing power supply.

CSO Workers have made significant progress extending the conduits trench further south from the power service pits laid three years ago, meeting up with another trench they’ve dug out which runs across the front of the south shed, and to a previously excavated pit on the highway side of the building. It is hoped this trench can have conduits and plumbing laid by next week, allowing it to be quickly filled in so as to allow minimal disruption to museum passenger services.
17th April
CSO Workers laid water piping and electrical/communications conduits within the trench running across the South Shed entrance in the hours before lunchtime, allowing it to be filled in by the end of the day.
24th April
Two electrical service pits have been installed and connected to several newly laid conduits in the railway facing trench. A further set of conduits are to be laid between the service pits in this area next week, before this trench can be filled in and work continued further south.

1st May
The rest of the conduits were laid between the newly installed pits, allowing the trench to be filled in by the afternoon. Currently the service pits are partially above ground, as it is intended to raise the height of the adjacent tram track in the longer term when it is relaid in concrete. This is will see the rails and pits level with each other.
